Automated PR Review

Keeping a 10-person team on the compounding side of quality.

Problem

As merge volume grew, a human reviewing every pull request became a bottleneck and an inconsistent quality gate.

Constraints

A small team that couldn't afford release toil; the need to catch first-order issues without slowing everyone down or breeding bypass habits.

Architecture

An automated PR-review framework wired into the CI/CD pipeline: every pull request runs first-line code-quality enforcement before a human looks, with Vercel preview deploys for visual review.

Trade-offs

Heavy gating adds minutes to every merge and a pipeline to maintain, in exchange for faster, safer, more consistent releases and reviewer attention spent on design, not lint.

Decisions

Shifted quality checks left into automation rather than hiring around the problem; kept the pipeline native to GitHub + Vercel to avoid owning more infrastructure.

Results

First-line defects caught automatically, human review focused on what matters, and a release cadence a small team can sustain.

Lessons

The cheapest reviewer is the one that never gets tired. Automate the boring half of code review and your seniors get their judgment back.
